Acoustic Performance of Recycled Glass Aggregate-Based Porous Concrete and Its Applicability through Café Space Simulation

Key Points

• This research aims to evaluate the acoustic properties of porous concrete made with recycled glass aggregate within café environments.
• Used recycled glass aggregate to create porous concrete samples.
• Simulated café space to assess acoustic performance of the concrete.
• Conducted sound absorption tests to measure effectiveness in noise reduction.
• Porous concrete exhibited significant sound absorption capabilities in the café simulation.
• Measured sound absorption coefficient ranged from 0.5 to 0.8 at various frequencies.
• Indicated improvement in overall acoustic comfort in the simulated café space.
